IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Lette-rs Patent No. 201,224, dated March 12, 1878 applicationfiled December 12, 1877.

Y To all whom 'it may concern: I

Beit known that I, JOSEPH WARRENGA- LEF, of North Easton, in the county of Bristol and State of Massachusetts, have invented certainnew and useful Improvements in Washing- Machines 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertainsvto make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in portable washing-machines, consisting` of a pair of longitudinally-corrugated rubber rollers, one of which is secured to a Shaft located in yielding bearings, and provided with y a crank by which it can be revolved. The other grooved rubber roller is made to run freely around a stationary shaft secured to the upright frames of the machine. The lower end of each upright frame is provided with an angular foot-piece, having a notch on its under side fitting into a holding-piece designed to be secured to the inside of the tub or other receptacle in which the washing is done. Each of said foot-pieces is open on one side for the reception'of the foot-piece of the frame, and is furthermore provided with a projection or guide fitting into the recess or notch on the under side of the foot-piece, and, finally, with a thumb-screw on the top for the purpose of fastening the foot-piece to the holding-piece. Said holding-pieces are arranged with their jaws opening in opposite directions, so that the frame of the machine can easily be inserted or removed from them by swinging the frame of the washing-machine on its center. The lower loose-running longitudinally-corrugated roller is provided with a central hollow metallic sleeve or tube tting loosely around the stationary shaft for the said roller.

Both rollers are preferably made with a core of wood or other suitable material, around which the longitudinally-corrugated rubber is secured; but I may also make the rollers of solid rubber, or otherwise, as may be desired. This machine has no bar or extension between the frames below the lower roller, which is generally considered as a great obstacle to the clothes that overhang the lower rolle-r during the progress of the washing. i

Withthis my improved machine I am able to wash clothing of thick or thin materials a great deal quicker rand with lessA eifort than could'A be done on any of the ordinary machines. The rotary longitudinallygrooved rollers, as they are rotated, press the clothes between them, and thus eifectual'ly cleanse and wash the same without the need of a rubbing-board, or without in the least tearing or defacing them.

On the accompanying drawings, Figure l represents a sectional elevation of my invention. Fig. 2 represents a cross-section over the rollers. Fig. 3 represents a plan view of the foot-piece of the frame and its holding piece, and Fig. 4 represents a cross-section of the foot and holding pieces on the line A B, shown in Fig. 3.

Similar letters refer to similar parts wherever they occur on the drawings.

a represents the upper, and b represents the lower, rubber roller. Both rollers are grooved longitudinally from end to end all around the circumference, as shown bythe grooves a a b b b. a represents the core of the upper roller, thatis iirmly secured to the crank-shaft c by means of the pins c c', or in a suitable manner. The shaft c is provided with a crank, d, by which it is operated. The said shaft c is made to rotate around its axis in yielding bearings c c in the frames e e, as shown. b represents the core of the lower roller, having a metallic tube or sleeve, f', that'iits loosely around the stationary lower shaft f, the latter being firmly secured to the frames e e by means of `nuts g g on the outside of said frames and collars on the shaft on the inside of the frames, as shown in Fig. l. h represents an upper brace or stay between the frames e e, above the upper roller a., which brace is provided with a suitable handle, h', by which the machine can easily be lifted out of the washing-receptacle, or otherwise transported with ease.` fi t' represent the foot-pieces, each forming a lower angular termination of each of the frames e e. Each foot-piece is provided on the under side with a notch or recess, 7c 7c, as shown. l l represent the holding-pieces into which the footpico-esi are inserted and secured when the Washing-machine is in use.f"Each`l1olding piece Z is provided With-aiiange,` m, thatis screwed or otherwise secured tothe inside of thek tub or Washing-receptacle, a portionV of which is shownV in Fig. 3;

V[Each holding-piece is formed of atop,V Z,-

bottom Z,and one close side, 15,the part opposite to the side 3'" being open, as shown, for

- the insertion of the foot-piece on the Washing-Y machine. The bottom of each holding-piece is f provided on the inside with a projection ork guide,k n, tting into kthe recessy or notchic on the underside of the foot-piece when the lat ter is inserted into the holding-piece Z.

. Eechholdin'g-piece is further provided with a thumb-screw, o; :as shown, bywhich the foot- Vpiece fi and holding-piece are firmly secured together when the machine is'in its proper position for use on the tub or other Washing y receptacle. f

Having thus fully described kthe nature,

' construction7 and operation of my invention, I

Wish to secure by Letters Patent and claim-'- 1. A Washing-machine consisting of one Y Y longitudinallycorrugated rubber roller, a a a',

' firmly secured to itsfshaft c, in combination with the longitudinally-corrugated rubber roller b la byprovided withv a central hollow nietallicgtube or sleeve, f', running looselyr on itsstationary shaft f, substantially :as and for v Y permit of vthe removal or insertion of the frame therein by achalf-tnrn of the frame, andpro-` vided with projections n imand the thumb` screws o o, to prevent lateral, vertical7 yor bori-A zontal displacement, substantially as and for the purposes set forth.4 Y v Y i v 3. The combination ofiframe e, having yield-k ing bearings c", with shaft c, to which is firmly Y e secured roller at a! ay and l roller b brb', sleeve fj', and shaft f,' substantially as andior the vpurposeset forth.

In testimony that I claim the foregoing as my ownv invention I have affixed my signature in presence of two witnesses. Y Y
